Postosuchus Size Comparison


Postosuchus 3D Viewer pairs published figure ranges for a Late Triassic rauisuchian - not a dinosaur - with a 1.8 m person: length panel baseline 5.5 m and mass panel baseline 500 kg within published ranges.


Postosuchus published figures

Compare four published Postosuchus size figures using the four points in this diagram.
Length 5.5 m, mass 500 kg, height 1.8 m, lived 227-208 Ma.

The Postosuchus facts panel and this table use the same real published measures:

MeasureFigureVs a 1.8 m person
Lengthabout 4-7 m (panel baseline 5.5 m)about three person-lengths at the panel baseline; Size vs human uses 5.5 m
Heightabout 1.8 m (panel baseline)near adult standing height at the back
Weightabout 250-1,000 kg (panel baseline 500 kg)several times a human body mass at the panel baseline
When it livedabout 227-208 Mya Late Triassic; Post Quarry Texas and North Carolinapanel era 227-208 Ma
Taxonomy noterauisuchian pseudosuchian; Chatterjee 1985; gait debate disclosednot a dinosaur; cautious quadrupedal reconstruction only; distinct from Sarcosuchus and Dimetrodon

How the Postosuchus size-vs-human toggle stays honest

The Postosuchus model is drawn to a fixed on-screen length; Size vs human places a 1.8 m person at the true length ratio to the 5.5 m panel baseline. Tap Size vs human under the canvas - the comparison is proportional, not a decorative sticker.


What a person would see beside a Postosuchus

What a person would see is a sub-erect quadruped archosaur whose panel length is 5.5 m beside a 1.8 m person - a cautious quadrupedal reconstruction with the gait debate disclosed. Turn on Size vs human and orbit.


What the Postosuchus size numbers are not

What these size numbers are not is a settled biped vs quadruped gait. Postosuchus was not a dinosaur. Soft-tissue color is still an artistic reconstruction. This model does not conflate Postosuchus with Sarcosuchus. This model is not a fossil-accurate skeleton. For controls see how to view Postosuchus in 3D.
